The travelling of forklifts in warehouses

Abstract

Around 75 % of warehouses retrieve products manually. In these warehouses forklifts are the most expensive machines. The study pays special attention to the travelling of these machines. In order to determine potential travel distance savings, a simulation model is created. The experiments demonstrate that the travel distance of forklifts can be reduced by 27-37 % when RF-based process is implemented comparing with travel distance when paper is used in the process. Research provided herein also defines how to optimize travelling by implementing multiple-tasks approach in WMS. The presented results show that the travel distance of forklifts can be also reduced by 9 % when multiple-tasks approach is used. In addition, it is identified, how stock accuracy affects the travel distance of forklifts. The correlation between the travel distance of forklifts and stock accuracy is presented herein.

A Comparison of Three Popular Routing Policies for Lift-truck Order Picking

“…As a result, the 90‐degree turns assumed in prior research on the traversal policy no longer hold when modeling lift‐truck movement in a wide aisle. Finally, modeling lift‐truck operations requires an adjustment to accommodate the size of the lift truck and a recommended safety gap between the lift truck and racks, reducing aisle width and impacting both travel distance and time (Burinskiene 2011, 2015).…”

Strategies for Enhancing Economic Sustainability: Modeling Reduced Bale Handling Costs in Cotton Warehousing

“…Griffin et al (2022) underscored the practical applications of distributed ledger technology within the cotton industry, specifically focusing on issues related to data quality assurance, sustainability metrics, and enhancing supply chain coordination. Additionally, Burinskiene (2011) and Burinskiene (2015) presented generic warehouse simulation examples. Hazelrigs et al (2017) delved into cotton warehouse operations by exploring alternative stacking and marketing techniques.…”

Modelos y métodos para el diseño de sistemas de aprovisionamiento a líneas de montaje con mezcla de modelos.

“…El objetivo de eficiencia ha sido ampliamente considerado en la literatura, siendo algunos de los medibles más utilizados los metros recorridos, los recursos requeridos, los envíos realizados, el rendimiento de los medios de manutención o el nivel de servicio. Burinskiene (2011) intentó reducir la distancia total de viaje de las carretillas elevadoras en los almacenes con un enfoque de tareas múltiples utilizando simulación. Longo, Mirabelli, y Papoff (2005) intentaron minimizar los costes del manejo de materiales determinados por el flujo de materiales y las distancias entre las máquinas.…”
